Chakradhar and Dhruva have two spools of 'manja' (a specially prepared thread) to fly their kites. Each of the manjas has tiny knots at regular intervals, which helps in keeping track of the length of the manja that is used. Each of the persons has the same length of manja. While Chakradhar's manja has knots at intervals of 10 feet, Dhruva's manja has knots at intervals of 12 feet. Also, Dhruva's manja has exactly 10 knots less than that of Chakradhar. If each of the manjas starts and ends with a knot, find the length (in feet) of the manja with either of them.

Consider a circle with unit radius. There are seven adjacent sectors, S1, S2, S3, ..., S7, in the circle
such that their total area is pi/4..Further, the area of the jth sector is twice that

What is the greatest possible area of a right angled triangle of hypotenuse 4 cm?
In how many ways can 18 identical candies be distributed among 8 children such that the number of candies received by each child is a prime number?
So now I distribute the 2 to everyone as it the minimum prime,so I'm left with 2 candles and I have to split this among 8 children so it is 9!/2!*7!..But the answer is 28,where am I going wrong?
